A grand slam in tennis is when a player wins all four major tournaments in a calendar year: the Australian Open, French Open, Wimbledon, and US Open. Achieving a grand slam is a rare and prestigious accomplishment in tennis history. It greatly impacts the outcome of a tennis match as it solidifies a player's status as one of the greatest in the sport.
The four major tennis tournaments; the US Open, the Open Championships(wimbledon), Roland Garros (French Open), and the Australian Open are known as the Grand Slam of tennis. Hitting a grand slam in baseball scores four runs and is the greatest accomplishment a baseball player can achieve during one at bat. Likewise, winning the Grand Slam of tennis involves winning four tournaments and is considered the greatest accomplishment in tennis. Because "tournament which makes up part of the Grand Slam of tennis" is so long it is usually shortened to "Slam".

Roger Fedora??? You mean Roger Federer? How could you get the name wrong of the greatest man and tennis player on this terrestrial planet? Alas, Roger lost in a five-setter to Rafael Nadal in the Australian Open in 2009 and to Juan-Martin del Potro in the 2009 US Open. He won Wimbledon as well as the French Open this year. The French Open cinched his career grand slam--winning all four major tournaments and Wimbledon cinched his record-breaker 15 grand slam titles beating out Pete Sampras' record of 14. Pete also never won the French Open, thus making Roger Federer the undisputed greatest tennis champion of all time.
Before the advent of the open era of tennis competitions in April 1968, only amateurs were allowed to compete in established tournaments, including the four Grand Slams.

A "grand slam" can mean two different things in tennis. Most people consider a "grand slam title" winning one of the four majors (Australian Open, French Open, Wimbledon, and the US Open) However, it can also mean winning all four of these events. If this is done during one season, it is most often referred to as a Calendar Slam (but can also be called a Grand Slam) and if a player wins all four of these events over the course of their career, it is accordingly called a Career Slam. Both are very rare.
